Title:
ION EXCHANGE MEMBRANE, METHOD FOR PRODUCING SAME AND ALKALI CHLORIDE ELECTROLYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/154925
Kind Code:
A1
Abstract:
Provided are: an ion exchange membrane for alkali chloride electrolysis, which is easily controlled with respect to variation in dimensional change without requiring a strict control of the residual amount of sacrificial threads in the ion exchange membrane; an ion exchange membrane precursor membrane; and an alkali chloride electrolysis device.
An ion exchange membrane for alkali chloride electrolysis, which comprises a fluorine-containing polymer layer having an ion exchange group and a reinforcing material that is composed of reinforcing threads and sacrificial threads and is provided within the fluorine-containing polymer layer having an ion exchange group, and which is characterized in that the average elastic modulus of the sacrificial threads is 1.0-7.0 GPa.
